I had some family go over to London for the Olympics and Truphone was the SIM i gave them. Other than taking some time to register, it worked flawlessly. I did have to work with Tru as the per minute pricing that I was charged did not match the prices on the web site. They did refund the difference, but it would be nice to not have to do that step.

During my trip to South Korea and the Piranha SIM worked good. The first time the SIM needs to register in a new network takes really long. Round about 30 minutes in South Korea. Back in Germany the SIM needed round about 12 hours to register in a network. During this time I have tried to register with different mobiles.

Does anybody knows what the reason for this is?

The Callback worked really good and the voice quality was also high.

Sometimes I was not direct reachable over the US number. The caller had to try 3 or 4 times to reach me.

The VOIP application worked for outgoing calls good with also a good voice quality. For incoming calls was the voice quality was really bad and I removed the VOIP application from my phone.

SMS are only working outgoing. I' am not getting any incoming SMS. Only the SMS from the Piranha support are working.

The prices are really good and I hope Pirnaha will be longer in business.

I have been testing [playing with] the SIM. I do get SMS sent to my US number. I did not get SMS to my UK number. This was from a US AT&T MVNO and a Philippine SMART SIM. This was done from California.
Sending an SMS from Piranha's web site worked for both the US and UK numbers.

Hi we are glad the Piranha Sim worked well in South Korea for you, unfortunately the incoming VoIP problem is dependent on the routes used by the calling party, we only use premium routing on VoIP and Voice calls which you described as good quality when calling out (thank you). SMS, we have tested your existing number and given you a new number to test SMS, we have sent you test texts from 4 different operators/networks, all of which have been received on your original and test number, please let us know where the texts you are talking about were sent from and the result i.e were you charged etc. Finding network, this is very unusual and only normally happens when a handset is left on flight mode, once we replied your support ticket, it was logged that your handset registered shortly thereafter.

PSIM.

P.S We expect to be around for sometime and thank you again for using our service.

Will be in China for 3 weeks as a tourist in April. For the past couple years I have found using T-Mobile's (U.S.) UMA wifi calling to be quite adequate since wifi was quite prevalent wherever we went overseas the past few years
This time I thought I'd look into an int'l SIM. Piranha seems to be the only provider to provide reasonable rates. Many charge over $1/min. Piranha charges 32 cents/min. for outgoing to U.S. and 19 cents/min. incoming. Question, has anyone here used them in China? The fact they are so much cheaper makes me wonder if I am missing something. The reviews, here, seem quite good. They make use of both carriers in China.
I read a review of China's own prepaids. Excellent and detailed, posting on the "Asia" forum here. Sounds almost impossible for a foreign traveler to make real use of it.

Any China travelers here? Is wifi easily found? Anyone use Piranha or another SIM there?

Thanks.
